I just replaced the servos and had a question about the brick (That's what the servos connect on to, right?). How securly do you have to glue it in there? The new servos look the same as the old so I figure I am going to replace them soon so I don't want to over glue but if the brick comes loose will the servos strip?

Also, I replaced the prop with the ember 2 shaft and on low speeds it sounds a little rough, sort of rumbles. Seems straight as an arrow and has plenty of power but I don't want to have to replace an engine in the near future!!
